Communication | RS485 |
Series | Acuvim, AXM |
Description
The AXM-RS485 module uses RS485 serial communication and the Modbus-RTU protocol, just like the on-board RS485 port of the Acuvim II series meter
- It provides a second RS485 port for serial communication, and it can work with the on-board RS485 serial communication simultaneously
- The terminals of communication are generally A, B, and S, where A is for the differential signal +, B is for the differential signal -, and S is connected to the shield of the twisted pair cables
- Up to 32 devices can be connected on an RS485 bus without repeaters
- Use good quality shielded twisted pair cable, AWG22 (0.5mm) or higher
- The overall length of the RS485 cable connecting all devices should not exceed 1200m (4000ft)
- Every A(+) should be connected to A(+), B(-) to B(-). Otherwise, it will influence the network or even damage the communication interface
- When using a long communication cable to connect several devices, an anti-signal reflecting resistor (typical value 120Ω-300Ω/0.25W) is normally added to the end of the cable beside the last meter to prevent communication quality degradation
